The last episode of season 16 partially takes place in Copenhagen.
The British head of a biscuit-making company, Eric Calder, eats one of his biscuits and dies while in Copenhagen to close a deal. Since the biscuits were sent from England, a Danish detective, Birgitte Poulsen calls on Barnaby to investigate the murder.
Well, for a biscuit-making company, this place has a lot going on. Eric's son, Harry, had recently fought with his father, and his wife is sleeping with his brother, Julian. Julian is later murdered by being drowned in alcohol. Then there is the very talented and knowledgeable baker, Armand Stone.
Barnaby and Nelson travel to Copenhagen, where they meet two female detectives, one of whom sparks with Charlie. A floral arrangement at Eric's funeral was paid for by a credit card stolen from Pastor Thomas Madsen. They learn that Eric was involved with Ingrid Madsen and they have a daughter, given up for adoption.
As all of this is going on, Barnaby's wife is very close to giving birth. Then there is another death.
Red herrings abound as Barnaby and Nelson dig up past secrets and learn the history of the company.
I thought this was a good episode and particularly sweet at the end. The murderer and the reason for the murders comes late in the episode, and Barnaby has just learned his wife is going to the hospital.
I really like Gwilym Lee as Charlie Nelson; he seems to have less to do than the other assistants did at the moment, but Charlie is an excellent detective.
Can't believe this show is still running; it's definitely the "Law & Order" of the U.S. as far as longevity!
